6LoWPAN Network and Protocol Analysis

The lately defined 6loWPAN is becoming an appealing alternative for sensor networks communication by combining the many benefits of IP based applications and protocols with the low power and communication link efficiency mandatory for wireless sensor networks.

While there are many tools in the market for analyzing wired IP as well as WiFi networks, non of these tools support 6LoWPAN with its unique RF and MAC layers.

Researches, developers and system integrators looking to design and implement 6LoWPAN sensor networks are lacking a professional analysis tool.

The Perytons 6LoWPAN protocol analyzer (also referred in the market as 6LoWPAN sniffer) is an indispensable tool for development, integration, installation, monitoring, and troubleshooting of 6LoWPAN systems, networks and products. Perytons analyzers combine full coverage of the 2.4Ghz band with a rich and user-friendly analysis toolbox. The Perytons analyzer allows full analysis of the communication layer, identifying network topology, time related transactions, message structure and more. The resulting IP messages constructed by the analyzer are then easily exported and ready for external standard IP analysis tools such as WireShark.

The Perytons' team keeps following the 6LoWPAN standardization efforts so that newly defined features and layers will be implemented into the analyzer, letting the users being up to date with the latest standard features.

The Perytons 6LoWPAN sniffer is fully compatible with other Perytons models, allowing to use the same tool for analyzing other 802.15.4 based protocols such as ZigBee. It also allows the user to build his own layers on top of the 6LoWPAN into the analyzer environment, thus creating a customized analysis tool that includes the user preferences and customization into the analysis platform of the company.

 

Multi-channel networks analysis

 Perytons Analyzer Time View Clip (46 sec)
While the free licensed 2.4GHz band is gaining use by more and more applications and protocols, there is an increasing demand of using multi-channel protocols. Along with that a sophisticated tool that allows simultaneous analysis of the channels plays an important role when trying to develop, deploy and optimize such networks.
The 802.15.4 PHY defines 16 possible communication channels in the 2.4Ghz ISM band. Perytons analyzers capture multiple channels simultaneously, enabling the analysis of dynamic processes such as “active scan” multiple networks operating in the same environment, or rogue devices which transmit on the wrong channel.[read more …]

Reliability
Especially when dealing with tough RF environments, the analysis tool used should reflect the actual network situation through the data it captures.
The Perytons analyzers are unique in the use of antenna diversity techniques, providing superior reliability through reducing the number packets lost due to RF indoor multi-path propagation conditions, and reducing interference from up to 15% to less than 0.1%. [read more …]
